Inca Empire and the Moche civilization

As I was reading from my text book, I came across a short section about the Inca Empire. This sections said that Incas incorporated the lands and cultures of earlier Andean civilization such as the Chavin, Moche, Nazca, and Chimu. The book just gives us this brief statement, leaving me with a lot of questions about these civilizations. How did they help the Inca Empire flourish? What new things did they introduce that were not present before? So I decided to do some research on one of these civilizations, the Moche. 

So first of all the Moche were a civilization that started in AD 100, and ended in AD 800. This civilization was located in the Northern Peruvian coastline, were they could easily access the lower river valley for a great amount of there resources. Their location provided them with a lot of resources such as clay an metal. This was really important to them because they were a really artistic civilization that used art as away of expressing emotions of everyday life. We are able to learn a lot more about this civilization only because of there art, which involved sculpting with clay, working with metal, painting and much more. This civilization also offered new technology to everyone around them. One of the biggest technological advancement of their time was the system of irrigation that they created. So the Moche offered a lot of ideas, and customs to the later Inca Empire.
